Re: [Amc-list] Flexplate & Mini-Starter Questions for 727 auto

[Greg Taylor <amundaza@xxxxxxxxx>]

Thanks to EVERYONE for the GREAT feedback.
   
  I have discovered that my Jeep mini starter can be had in a 1.7kW unit, similar output to some of the other mini starters for AMC/Jeep units.
   
  Jim, are you saying that the torque converter on my '89 GW fits differently and subsequently, if I were to switch to an earlier flexplate to run an AMC mini starter, that I would have to swap torque converters also?
   
  Thanks,
  Greg Taylor :)  <><

  Keep in mind that if you want to run the later starter, you need the later flexplate (tooth offset is different. Same as AW4, but the converter fit is different too.)

I am planning to buy a 6-cylinder flexplate for the neutral-balance build on the 304 stroker motor. This will be replacing the weighted flexplate for my 1989 Grand Wagoneer's current 360.

I have researched the various flexplates at www.partsamerica.com for a 1989 GW (360, weighted) a 1989 YJ (258 non-weighted) and a 1980 GW (258 non-weighted). They all are the same diameter, same tooth count and pitch. The 1980 258 unit is about $20 less than the 1989 258 unit (YJ).

I would like to run a high torque mini starter, in place of the stock Chrysler "mini-starter", since I'll be pushing 10:1 compression with the stroker. I had talked with a guy on Ebay (happens to live not far from my work), who sells Mini-starters and he said that the mini-starter would not work with my 1988+newer GW 727.

Is there something different about the 1988+newer trannies or flexplates, that would prohibit the use of the mini-starter? Are the bolt holes different in the tranny and/or starter?

Could I run the 1980 258 flex plate and then use the high-torque mini starter?

Is the stock Chrysler 'mini starter' strong enough to handle 10:1 and should I just stick with it? Please keep in mind that I still have to swap from a 360 flex plate, to a neutrally balanced (no weight) 258 flexplate for my stroker build (it will be internally balanced).

Also, the stock mini-starter has full power to it and then a supplemental ignition wire that engages the starter. Could this be why a mini-starter won't 'work'?

Thanks for the feedback, all!


Sincerely,
Greg Taylor :) <><
